To'all whom "it may concern:

Be it known that I, CHARLES D. WARD, a citizen of the United States, residing at New York, in the county of New York, State of New York, have invented a certain new and useful Improvement in Calculating-Machines, of which the following is a specification.

My invention relates to calculating machines and has for its object to provide a new and improved machine of this description which will print on a strip of paper a series of rows of figures, make a summation of such figures, and print the total in its proper place at the foot of such. column of figures.

My invention is illustrated in the accompanying drawings in Which- Figure 1 is a longitudinal, sectional elevation, with parts of the mechanism broken away to show the interior arts. Fig. 2 is an end elevation looking in t c direction of the Fig. 3 is a transverse sec-v tional elevation on the line 33. Fig. 4 is a plan view with part of the printing mechanism broken away. Fig. 5 is an end elevation looking in the direction of the arrow in Fig.

1 and showing the mechanism in position for printing the total. Fig. 6 is an enlarged de. tail view in cross-section of the outer portion of the numeral wheels.

Referring to Fig. 1, AA are the side frames of the machine in which is mounted a shaft C for supporting the numeral printing wheels and their associated mechanism.

At the left hand end of the shaft is a securing nut E and at the right hand end a screw threaded sleeve D carrying the operating handle D and its arm D The calculating mechanism comprises a series of numeral wheels R, loosely mounted on a sleeve B on the shaft 0, the wheels havi'ng on their outer rims a series of figures 30 (see Fig. 6) raised like type, to enable them to print. These numeral types are arranged in groups of ten, six groups beingshow'n, al-

- though, of course, any other number might be used, the purpose of using a series of groups being to permit the employment of a wheel of comparatively large'diameter the ing a better printing surface than would one of smaller diameter.

Each wheel is recessed near its periphery on both sides, and in one, of the recesses are arranged the ratchet teeth R, and in the other recess are located the spring pressed Specification .of Letters Patent.

pawls T (see Fig. 6) having laterally extending fingers for engaging the teeth R of the adjoining wheel.

Between the wheels are located the carrying and resetting disks U'secured to the sleeve B surrounding the shaft C. These disks U are of the circular shape shown in Fig. 3, but have depressions U and projections U The laterally projecting arms of the awls T nor- .mally ride upon the edge-of the isk U, thereby being held out of contact with the teeth of the ratchet R on the adjoining numeral wheel. When the pawl T reaches the depression U, it is permitted (as shown at the right hand-of Fig. 6) to engage a tooth and rotate the adjoining wheel a distance of one tooth, after which it rides u and over the projection U to the surface of the disk. As each ratchet wheel has ten teeth between each two de ressions, it will be seen that when one of t c numeral wheels is given onesixth of a complete revolution or ten teeth, it will carry the adjacent wheel forward one tooth. Each of the numeral wheels. also has a series of ratchet teeth R which are engagedby spring pressed stop pawl R mounted on the frame to prevent the backward movement of the numeral wheels, and to also insure their proper alinement.

Mountec above the numeral wheels are a series of numeral segments X arranged to move in dovetail grooved guides l/V.

The guides W are shown as provided with as many grooves as there are numeral wheels, and are curved concentrically with such wheels. Each of the numeral segments X has at its under side a spring pressed pawl a, which engages with the teeth R of the corresponding numeral wheel R and causes that wheel to rotate about its aXis through the same are as the segment X. Each segment has on its'outer face a series of numerals arranged as shown from 0 to 9, with a blank space ahead of the 0 so that a series of zeros need not appear before a number having less than ten figures. Between the numerals are holes or pockets into which a rod or stylus can be inserted in order to move the se ment X.

n addition to the numerals above referred to, which are for indicating purposes, these segments are provided with an additional series of printing numbers from 0 to 9, properly positioned for printing and arranged with reference the printingpoirtso that. a

row of figures will be printed corresponding to that indicated at the stop bar I) by the in.- dicating numerals on those segments which ha'v'ebeen operated. As these segments or members, provided with indicating numerals, are located at the front of the machine so that the indicating numerals can be seen by the operator, theywill, after they have been successively operated, present to view, in a row, just above the stop bar, the number which is afterward printed. These segments having the numera'l's'on them are indicating devices hereinafter referred to, though it is not intended to limit the claims to the precise construction shown.

The guides W are carried between disk shaped end plates 11 which are supported on the sleeve B. Secured to the right end plate 1 is a pin 2 projecting through a segmental slot 3 in the end frame A, this pin carrying at its outer end an arm 4 having a handle 5. This arm has secured to its outer face a pin 6, and to its inner face, a cam piece 7- having at its end a projection 8 for engaging a notch 8 in the side frame, this end 8 being also provided on its outer side with a notch for engaging a bent spring 9 secured to the 1 frame. The spring 9 normally holds the arm 4, and the attached frames 11 in the posi tion shown in Fig. 2. The cam piece 7 has at its left hand portion a, curved surface 10 which is adapted, when the arm 4 is rotated about the pin 2, to be guided along the outer curved surface of the side frame A, whichis provided with a notch 11, corresponding in shape to the end of the cam piece 7 and adapted to receive-the same when the arm 4 is swung to its extreme position, as shown in Fig. 5. The slot 3 is of such length that "when the pin 2 is moved to abut against the left hand end of the slot, the end plates 11- and associated adding and printing wheels will be at the pro er position for printing totals. l'Vhen in t iis position, a further rotation of the arm 4about the pin 2 will cause the engagement of the pin 6 with an arm 12, (see Fig. 5) this arm 12 being secured to the sleeve D of the handle D. The downward movement of. this arm 12 causes a rotation of the shaft C and the sleeves B located between the. shaft and the frame. sleeves B has secured thereto arms 13. and 14, extended in op osite directions, and arranged to operate t 1e rinting mechanism in the manner which will be referred to later.

The printing mechanism is carried by a pair of plates H, H which are of the shape shown in dotted lines in Fig. '2. Supported by these carrying plates are a paper roll L and rubber feeding rolls K, of the usual type of rinting mechanism, J being a printing rib on stretched between two spools and arranged to wind from one to the other in the usual manner, the aper being automatically fed to the rolls by each printing move- .Fig. 2.

Each of these ment, in the manner usual in devices of this kind. slide in guides G, G secured to the side frames of the machine.

Carried by the plates H, Hare a pair of pivoted. spring-pressed hook ,devices 15 adapted to' engage the ends of the arms 14, the hook shaped portion 16 of said device 15 being so shaped that'as the arm 14 rotates, the end of the arm will first engage the hook and pull down the printing plates H, so that the printing operation will be effected, and then pass by the hook, which will, owing to the operation of its spring, return to its normal position. Springs 1.7 secured to the frame serve to restore the plates'H to their normal position. Pins 18 are secured tothe plates H in position to engage the arms 13, which by their downward movement cause a sufficient depression of the lates H to cause the totals to be printed. A so secured to the sleeves B are arms d carrying a cross bar e. This cross bar (2 serves as a resetting device for the numeral segments X, in'the manner to be described. later. Pins 19 roject outwardly from the side frames A, X, and serve as stops to prevent too great movement of These'plates.H,.H are arranged to the, arms D in the resetting operation. This arm has also connected to it one endof a spring 20 the other end of which is connected. to the frame, to restore the arm D and its connected parts to the position shown in T he sleeve B has secured thereto at its left hand end a resetting disk P provided with a series of handles Q. This resettingv disk has a series of apertures corresponding in number to the number of groups of tens on the numeral wheels R, into which apertures a projection carried by a spring S will dro when the wheels are reset to zero by the bac ward movement of the sleeve B and the resetting disk P. This resetting mechanism is of a well known type and need not be further described. v

The operation of the device is as follows The numeral wheels R and numeral segments X are first set at their proper zero points. When it is desired to make a record and summation of severalrows of figures, the operat ing stylus is inserted into the hole at or below the numeral in that one of the segments representing units, and pulled down until it strikes the sto bar I), l ig. 3. T his operation is repeate until a whole row of figures is indicated, on the segments which have been pulled down, just above the bar 7). This same row of figures will appearat that point on the segments just under the ribbon and the paper on the roll K, ready to be printed, which printing is accomplished by pressing down the handle D. The rotation of this handle D causes the engagement of the arms 14 with the hooks 16 of the pivoted devices 15, thereby causing a downward the paWls a with the ratchet teeth R to count the number which is indicated on the adding and face of the segments, the Wheels carrying the successive amounts in a manner well known in devices of this hind.

To printthe total, the handle Swith its arm 4 is movedto the left,.th'ereby disengaging cam piece 7 from the spring 9. A continued movement of'the arm 4 carries with it the end plates 1*1 and rotates all the parts that are carried by the sleeve Bnntil 5 the pin 2 strikes the left hand end of thelslot 3, when the parts will be in a position as shown in'dotted lines in Fig. 5, in'which posit-ion, it will be noted, the numeral segments and guides'have been rotated to the left a distance sufficient to expose} the numeral wheels with their printing types in position to cooperate with the .printingmechanism. In order that the printing mechanismimay be operated in this position, the arm 5 is turned about rod 2 as a pivot, until the pin 6 strikes an arm 12 which by further movement willrotate the shaft Q and the arm 13 carried there- I by, the arm 13 engaging with the pins 18 on the printing plates H ll, thereby causing them to move the printing mechanism down ward to print the total presented by the addingwheels at the printing. point. A backward movement of the arm 4 to the position shown in Fig. 2 rotates the parts to their nor mal position, and rotation of the wheel P resets the adding wheels to zero.
